Abstract

Changes in transverse refractive index induced by the photoelastic effect are calculated when an optical fiber is subjected to a uniformly applied diametral stress. For moderate values of the force per unit length applied to the fiber, we find that regions of comparable or higher refractive index than the core may be induced in the outer region of the fiber. Thus the stressed region is capable of acting as a mode converter that affects the transmission characteristics of the fiber and may enable coupling of energy in or out of the fiber.
